TURNSTILE.

Application filed May 26,

This invention relates to One'of the objects of this invention is to produce a turnstile gate which will operate 5 effectively and occupy a minimum of space, and preferably will occupy a space only sllghtly greater'than the length of one of the arms instead of more than double the liplgth of arms as in the conventional turns e. 1

Another object of this invention is to produce'a turnstile gate by which a passageway at one side of the centerof rotation or axis thereof will be obstructed by one of the turnstile ar'mswhich must be rotated in order to pass, while another. parallel passageway at the\ opposite side and adjacent to said center of rotation will be freed from th obstruction of the said rotating arms.

Another object of this invention is to produce a turnstile in which a series, and preferably four arms will be so' mounted to retate that each of such arms will successive- I be movedto extend in a horizontal direct1on to produce an effective obstruction for a passageway at one side of the axis about which it rotates and will thereafter, after movement through such passageway, be folded during its continued rotary movew ment at the opposite side of such center of rotation so that the space at said opposite side will be economized and another passageway free from obstruction may be positioned closely adjacent to said center, or another turnstile may be mounted to have the end of its arms extend into close proximity to said center or axis of rotation.

.Another object of my invention-is to produce a car vestibule in which a turnstile having foldable arms-may be mounted to obstruct an ingress passageway at one side of the center of the turnstile and to free an egress passageway from the obstruction of said turnstile arms at the opposite side of the said center.

Another object of my inventionis to pro- 7 ducea car vestibule'having a turnstile guard rail extending transversely therein to divide the space into ingressand egress passage:

ways and to provide a turnstile having its 'center of rotation" adjacent to or within said a guard rail, and means for successively extending and folding the turnstile arms to successively obstruct the ingress passageway atone side of said guard rail. an'd to' free from the normal obstruction of said arms 1924. Serial No. 715,823.

the egress passageway at the opposite side of said guard rail.

Withthese and other objects in view, the invention I comprises the combination of members and arrangement of parts so comco bined as to co-act and cooperate with each other in the performance of the functions and the accomplishment of the results herein contemplated. and'comprises in one of its adaptations the species or preferred form ii: on lustrated in the accompanying drawings, in which Fig. 1 is a fragmentary horizontal so tion of a car showing in plan the vestib'u and adjacent floor portion with my turnsti, to mounted in said vestibule;

1 Fig. 2 is a section, on the Fig. 3 is a side elevation from the rear or folded side of the turnstile, the guard rail being removed;

Fig. 4 is an enlarged plan view of the turnstile proper and mechanism for operat-. ingthe arms;'and

Fig. 5 is a plan view of a modified form of so my invention in which the cam is provided with inclined portions at opposite ends to. permit operation of'the turnstile in opposite directions.

Referring now to these drawings, which illustrate a preferred embodiment of my invention, T indicates my space-economizing turnstile which, in the preferred embodiment shown, is mounted in the vestibule 2 of a car 1-, which vestibule is usually of quite limited space and 's usually separated from the inner compartment 3 of the car by a partition or step 4.

In the saidpreferredembodiment shown, the vestibule is provided with the usual ingress passageway'5 and a parallel egress passageway 6 closely adjacent thereto. These passageways usually register with ingress and egress doors or doorways 5" --6 and are usually provided at opposite sldes of a central post 7. Between and separating the passageways 5 and 6 and preferably 1n alignment'with the post 7, I mount a relatively narrow dividing element such as the turnstile guard 8 and arrange'the center of,

line 2-2 of Fig.

rotation 9 ofany-turnstile T closely adjacent to the plane of said guard 8. By the use of a turnstile having foldable arms and locating the center thereof as aforesaid, I am enabled to obstruct the passageway at one side of the said guard 8 and to completely free 'from obstruction of the rotating turnstile arms the passageway 6 at the opposite side of said guard and center of rotation.

In the preferred embodiment illustrated, a turnstile post P is suitably secured to the floor intermediate the opposite ends of the guard and adjacent to one sidethereof. At the upper end of said post P, I mount a rotatable element or arm carrying head 10 which, as illustrated, comprises a circular collar 11 composed of an angle iron having a horizontally extending flange 12 provided with a ball race 13 to permit the mounting of the head 10 on a flange 14 cast integrally with the post P by means of ball bearings 15. The said head 10 is, in the embodiment shown, provided with a series of four bearing brackets 16 each having pivotally mounted therein a foldable turnstile arm A. As illustrated, each of the arms A is pivoted on a (pivot pin a in the brackets 16 and is cause to swing on its pivot in one direction and, as shown, to an n ward, horizontally, passage-obstructingposltion by means ofa spring 17 which is wound about the pivot pin a, has at one part an abutment against an inward extension 18 of the arm and at another part abuts against the twin members of the bracket 16. Obviously the normal action of the s rin raises the arms A into' the normal horizontal or passage-obstructing position. I therefore provide means for successively, during rotation, moving each of the armsA against the action of the said spring 17 to fold the same. This is accomplished when in the rotation of anarm on and bythe rotatable element or arm-carrier,

it has passed through the ingress passageway in extended or obstructing position and has reached the point where it would normally extend into the egress assageway. It

is, of course, desirable to ree said egress passage at the opposite side of the center of rotation from such arms, and, in the embodiment shown,-I provide means for lowering the arms against the action of the spring. As illustrated, I provide the end of each of the inward extensions 18 of the, arms A with a ball-roller 19. These ball-rollers ride when the arms are extended horizontally on the horizontal] -disposed portion 20 of a cam track forme in the upper surface ofa casting C. The said castlng is also provided at one side with a raised or inclined cam surface 22 which, during rotation of the arm, engages its ball and, the extension 18 acting as a lever, each 'of the arms A as they engage the cam surface will be folded downwardly into a substantially vertical position and will be held in such vertical position untilthe continued rotation of the arm carrying head 10 causes the arm so acted upon toreach a radial position parallel with the ingress passageway and guard .rail,

whereupon the termination of the raised cam-surface 22 will permit the arm to be raised by the spring 17 and to continue its next cycle of movement in raised or horizontally-extended position. In the preferred embodiment shown, a portion of the casting C overlies the flange 12 of the rotating member and retains the same in place on the flange 1+1 of thepost P. As illustrated, the casting C has a core portion a which fits within the hollow post P and is connected thereto by a pin 21.

In Figs. 1 to 4 I have shown a construc tion in which the arms. are adapted to be rotated in one direction only. Obviously by providing the raised cam surface 22 with an inclined portion at opposite ends, as more particularly illustrated in Fi 5, the arms may be rotated in opposite directions. It is desirable during their rotation through the'ingress passageway which it is desired to obstruct, to prevent a depression of the arms and for this purpose the cover plate 23 is arranged" to engage each of the balls 19 during their horizontally-extended and arcuate movement through said ingress passageway.

Having described my invention, I claim:

1.' A turnstile gate having a series of arms mounted torotate about an axis, a spring for raising such arms to extend horizontally during a portion of the rotary movement thereof at one side of said axis anda cam device adapted to move such arms against the pressure of the said spring for lowering such arms into substantially vertical position during that portion of rotation atthe opposite side of said axis, whereby a pa s sageway adjacent to one side" of said axis may be obstructed by such arms and a passageway adjacent to the opposite side may be freed from obstruction y such arms.
